Okay, that makes sense. I *should* be able to get hold of some of this
"mu-metal" stuff - I know people at an electicity/electronics R&D lab....

Ahem. Yes... Typing to quickly for my brain again, I'm afraid.
1st attempt:
"build" some shielding out of aluminium foil to go around the
transformer. Which I did - all rough & ready stuff, with just a bit of
Aluminium won't do a darn thing about 50Hz magnetic fields. You want
something like mild steel, or better still mu-metal (if you can get it at
a sensible price, or indeed, at all). Clearly,
therefore, the wobble is induced by the monitor. There must be a
^^^^^^^
transformer, surely... Now, if half of that goes open-circut (dead diode, bad
connection, etc)
the machine will most likely still work, but the stray field from the
transformer will increase. It's worth checking this...
I will have a poke around with my multimeter tomorrow...
